Hi, I’ve had my 2010 Forester in for all maintenance with the dealership. Shortly after the timing belt was changed, the head gasket blew at 170,000 km. Replaced that. Now the engine constantly makes a loud ticking sound and it’s down 1 L oil every 1,000 km. I took it in to the dealership for a diagnostic. Charged me $250 to tell me the engine looks average, plus another $200 (without asking) to fix an open pcv valve. It still ticks loudly and burns oil. Seems like the engine is done. Is it time to sell if I’m not a mechanic? This car has cost me a fortune this year ($8,000)!!!! And I feel like the dealership is just trying to wring every last cent out of me before this engine gives out.
